Question

express using positive exponents then if possible simplify 1 over z^-6

Answer 1

What is to be expressed ?

Answer 2

that is what i am trying to figure out

Answer 3

it can be written as (z^{-6})^{-1}

use the power of a power law

\[(x^a)^b = x^{a \times b}\]

Answer 4

so is that my answer I do not understand this

Answer 5

oops should be

\[(z^{-6})^{-1} \]

Answer 6

How do I get my answer please explain

Answer 7

since the negative exponent is in the denominator, make it a positive exponent and put it in the numerator
\[\frac{1}{b^{-n}}=b^n\]

Answer 8

ok i got that then what?

Answer 9

use the index law for power of a power

\[(x^a)^b = x^{a \times b}\]

so multiply the powers you have in the question.

Answer 10

ok I will try
